Short focal length view camera lenses are not retrofocus designs. Infinity focus is achieved when the rear nodal point is one focal length away from the film plane. This is why the flange focal distance (essentially the distance from the lens board to the film plane when focused at infinity) is fairly close to the focal length of the lens. They are are more or less symmetrical in design around the diaphragm - which is another way you can tell they are not retrofocus designs. A retrofocus lens is asymmetrical in design, with a negative element/group at the front. The purpose is to move the rear element further away from the film plane than it would normally have to be for a given short focal length, so that there is room for say a reflex mirror to swing up and down behind the lens. There is no such obstacle in a view camera - although obviously retrofocus wide angle lenses could reduce the need for accessories like bag bellows. The disadvantages are complexity, size, weight (lots of elements) and - usually - distortion.
Compare the designs of a typical RF 21mm lens (Zeiss, Leica etc) or even a 75mm 4x5 lens with a high quality 21mm SLR lens. In the highly corrected RF lens you'll find maybe 8 or 9 elements, 7 or 8 elements in the view camera lens, and up to twice that amount in the SLR lens. Compare say the Zeiss 21mm f/2.8 ZF SLR lens with a Zeiss 21mm f/2.8 Biogon RF lens. Both excellent, sharp lenses. But the Distagon uses twice the number of elements to get there, and still exhibits some visible distortion.
